Currently the findmin/findmax functions in CUDA are defined for cases where one passes in them only a single CuArray ([link](https://github.com/JuliaGPU/CUDA.jl/blob/243c4ae90f9d48a0384b6e711f3563fed125b1b3/src/indexing.jl#L83)), e.g. `findmin(a)`. However, findmin/findmax functions in Base allow to pass in them an additional function as the first argument, e.g. `findmin(abs2, a)`.  
Would it be hard to extend the existing definitions of CUDA findmin/findmax functions to match the functionality of Base?
